WINDOW, ESPECIALLY FOR RAILROAD, TRAMWAY, AND OTHER VEHICLES.

Application filed July 6, 1920. Serial No. 394,399.

Be it known that I, AR'rUR MoLLnNKorr, citizen of Germany, residing at '73 Konigstrasse, Lubeck, Germany, have invented certain new anduseful Improvement in Windows, Especially for Railroad, Tramway, and Other Vehicles, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to windows for vehicles, and it has for its objects, among others, to provide. a novel construction whereby the window can be easily turned into the various desired positions and reversed for cleaning or'other purposes.

Other objects and advantages of the nvention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawing, which, with the numerals of reference marked thereon, form apart of this specification, and in which Figure 1 is an elevation with portions broken away and parts in section.

Figure 2 is a vertical section.

Figure 3 is a detail partly in horizontal section.

Figure 4 is a vertical section showing the window in one position.

Figure 5 is a similar view showing the window in a different position.

Figure 6 is a similar view showlng the window in still a different position.

Figure 7 is a sectional detail with the parts in still a different position. I

Like numerals of reference indicate like parts through the different views.

In the drawings:

1 designates awindow frame in which are aflixed the boxes 4. Each box is provided, within the same, with a curve 6 havting a stop member 7. A two armed member 89 has one end or the other co-operate with this curve and stop, as shown clearly in Figures 2 and 7. This member or lever 8-9 is carried by the pin 11 carried by the sash 10, as seen clearly in Figure 1. This pin works in therectangular opening 5 1n the box 4, as seen clearly in Figures 1, 2, 4, 5, 6 and 7. The turning point when the sash is swung out is changeable, describing, as it were, a quadrangular outline, as will be readily understood from the various views.

12 is a spring'affixed at one end wlthln a:

corner of the box, as seen in Figures'2 and 4 to 7, with its free portion bearing against the pin 11, and assists in the movements of the sash and to keep the same tight in its closed position.

fAt the upper and lower edge (5f the frame are ledges. As seen in F igure 2, the bot-- tom member. '2 has the grooved ledge 15, while the upper member 3 of the frame has a catching ledge 16 on the outside, and the projections 13 and 14 cooperate therewith,

as seen in Figure 2. The loweredge has a lifting handle 17 and the similarhandle 18.

The operation is as.follows:. I? Supposing theparts to be in the position upper edge has a seen in Figure-2, the sash is liftedmby the handle 17 until the member'13is moved out of the groove 15 and the arm of the lever is brought out of the curve away from the stop 7. The upper sash slides upward on the ledge 16 and the pin 11 lies against the upper edge of the cut out 5, as seen in Figure 4. Now the lower edge is pulled outward from the frame so that the member 14 stands against the ledge16, and the pin 11, againstthe influence of the spring 12,

is pulled over the cutout to the opposite" side. Then a pull of the sash downward will bring the upper edge out of its engagement with the frame and the pin 11 takes its lowermost position in the cut out 5, as seen 1n Flgure 6, and the lowermost arm of the lever corner. comes in contact with the 1nof the ofiset or stop .7 and thus the turning I movement is started. Now, by lifting the handle 17, the upper part of the sash swings downward so that the arm 9 rides on the curve 6, as seen in Figure 7. The arm 9 slides downward on this curve and lifts the sash so far as to permit the member 14 riding on the incline 20 and jumping into the groove 15. The pressure of the spring 12 prevents all rattling of the sash when closed.

What is claimed as new is v 1. A window structure comprising a frame provided with'an .upper crossbar and a sill,

a sashreversibly mounted insaid frame with.

the rail at thetop thereof normally spaced from the horizontal surface of said crossbar and the rail at the bottom normally engaged With said sill, and means for swingingly associating said sash with said frame, said means comprisin a box carried by a jamb of said frame and provided with an opening and a pivot pin carried by the sash and extending into said opening, the distance between the opposite walls of said opening being greater than the diameter of said pin whereby the sash may be raised to clear the sill, then moved laterally and downwardly to clear 1 the lintel, and then swung toward reversed position While the pin rests onthe bottom wall of the opening.

a 2. The structure according to claim 1 wherein there is a cam shaped member in the box adapted to support said pin. I

3. The structure in accordance with claim 2 wherein said pin comprises oppositely extending arms adapted to engage the said cam surface as the sash moves-toward reversed position to raise said sash, whereby the rails at the top and bottom thereof may be brought into normal relation with said cross bar and sill respectively.

4. A frame, a box thereon with a rectangular opening, a sash in said frame, a pin carried by the sash extended into the box through said opening and laterally movable in the latter and engageable with the Walls of said opening, a two-armed member carried by said pin, and a cam surface in said box with which the end of either one of said arms is adapted to engage, said pin and member reversibly supporting the sash.

5. A frame, a box thereon with a rectangular opening, a sashin said frame, a pin carried by the sash extended into the box through said opening and laterally movable in'the latter and engageable with the walls of said opening, a two-armed member carried by said pin, a cam surface in said box with Which the end of either one of said arms is adapted to engage,- said pin and member reversibly supportingthe sash and a stop member at one end of said cam to limit the movement of the engaging arm along said cam surface.

In testimony whereof I aflix my signature 'in the presence of two witnesses;
